How this service works
Email checks, DNS and email-authentication audits, website contact extraction, SEO audits, URL to Markdown and Swedish validators, paid per call in USDC with x402.
Output
A JSON object with: `valid` (boolean), `errors` (array of validation error strings, empty if valid), `country` (ISO 2-letter country code), `formatted` (space-grouped human-readable IBAN), `normalized` (compact IBAN without spaces), `bban` (Basic Bank Account Number portion), and `check_digits` (2-digit checksum string).
Example use cases
Pre-transfer IBAN sanity check
“Before I send this international wire, can you validate the IBAN DE89 3704 0044 0532 0130 00 and confirm it's correct and which country it belongs to?”
User-submitted form data verification
“A customer just entered the IBAN FR76 3000 6000 0112 3456 7890 189 on our payment form — can you verify it's valid and return the normalized version so I can store it cleanly?”
Extract bank details from IBAN
“I have the IBAN GB29NWBK60161331926819 — can you parse it and give me the BBAN, check digits, and confirm it's a valid UK account number?”
Technical details
Endpoint
GEThttps://agentkit-x402.erikssonanton2001.workers.dev/v1/iban?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call IBAN validation without setting up a dedicated banking SDK or subscription service. Ideal for AI agents that sporadically validate IBANs as part of a payment or onboarding workflow, since the $0.001 USDC per-call pricing means no wasted spend on idle subscriptions. Prefer this over free regex-only checks when you also need parsed output like BBAN, country, and formatted string.
Side effects
- Missing `iban` query parameter returns an error response
- Invalid or malformed IBAN returns valid=false with a descriptive errors array
- Unsupported or unknown country prefix may return valid=false
- Payment failure (x402) if USDC balance is insufficient or wallet not configured
